BUc we muft not take our leave of this fubjeft, untill we 

 have examined, how motion bcginncth in liring things; 

 as well plants as fcnfitive creatures. We can readily pitch up- 

 on the part we are to make our ebfervations in, for retriving 

 the engine of this primary motion : for having concluded that 

 the roots of plants, and the hearts of animals are the parts of 

 them which are firft made, and from which the forming virtue 

 is derived to all the reft, it were unreafonable to feck for their 

 firft motion any where elfe. 



But in what manner^ and by what means, doth it beginne 

 there? for roots, the difficulty is not great : for the moyfture 

 of the earth preffing upon the feed, and foaking intt> it; the 

 hot parts of it which were imprifbncd in cold and dry ones, 

 are thereby ftirrcd up and fetoiVwork: then they mingling 

 thcmfclves with that moyfture, d'o ferment and diftend the 

 whole feed ; till making it open, and break the skinne more 

 juSte cometh in : which incorporating it felfe with the hear, 

 thofe hot and now moyft pares will not be contained in fo nar- 

 row a roome as at the firft ; but ftruggling to get otit'on all 

 fides, and ftrivifig to enlarge themfclves, they thruft forth lic- 

 tle parts : which, if they flay in the earth, do grow white and 

 make the root; but thofe which afcend, and make their way 

 into the aire, being leflc comprcfTcd, and more fuH of heat 

 and. moyftnre, do turn green : and as faft as they grow up, 

 new moyfritre coming to the root, is fent up through the pores 

 of it : and this faileth not, untill the heat of the root it felf doth 

 fail. For it being the nature ofhcat to rarifie and elevate, 

 there muft of necefTity be caufed in the earth a kind of fuck- 

 ing in of moyflure Into the root from the next parts unto it 

 to fill thofe capacities Which the dilating heat hath made that
